#GLF 1.0
#D 4-bit binary counter
#D A p736 (= 46 * 2^4) gun based on 4 boat-bits which form a binary
#D counter.  (A boat-bit is a memory device in which a bit of
#D information is represented as the presence or absence of a boat
#D adjacent to a snake (or eater or beacon or ...).  Hitting the
#D boat-bit with a glider changes its state.  The transition from
#D 1 to 0 can be detected by another glider.)
